Cross-section of brain, June 1960

Posterior coronal view of the head. Depicts management of a left subdural haemorrhage with associated ipsilateral tentorial herniation through the foramen magnum. Subdural haematoma is drained via burr hole while fluid is injected into the lumbar spinal subarachnoid space – allowing upward pressure to be exerted on the herniated brain tissue, thus shifting it back to the correct anatomical position. Note: annotated on the back of the drawing is "Mr. Shaw, Wd. 20, June 1960". Mr Shaw was a Consultant on Ward 20.
